Vacuum cleaner having a wet duster device

Abstract

A vacuum cleaner comprising a moisture cleaner device which is easily attached and removed. The moisture cleaner device comprises a frame providing the circulation track of the moisture cleaner; a working roller and a driven roller mounted sideways in the top and lower part of the said frame; a first coupling means for attachment and removal of the lower part of the moisture cleaner to the vacuum suction head section; a second coupling means for attachment and removal of the top part of the moisture cleaner to a connecting pipe; and a moisture cleaner mounted to the surface of the frame. Because the peripheral surface of the working roller is uneven, when the vacuum suction head portion is moved back and forth, the working roller and driven roller are rotated, the moisture cleaner thus being operative such that the moisture cleaner contacts the floor as the normal vacuum suction cleaning proceeds.

What is claimed is: 
     
       1. A vacuum cleaner having a moisture cleaner device comprising a primary body accommodating a motor fan and a filter to provide a vacuum suction; a dust vacuum suction head portion at the bottom of the body for sucking up dust on a floor; and a connecting pipe connecting the primary body to the dust suction head portion in which a top part and a lower part of the moisture cleaner are adapted to attach to and be removed from the connecting pipe and the dust suction head portion, the moisture cleaner being positioned external to said dust suction head portion. 
     
     
       2. A vacuum cleaner as in claim 1 in which the moisture cleaner comprises a frame for providing the circulation track of the moisture cleaner; a working roller mounted in the lower part of said frame; a driven roller mounted in the top part of said frame; the first coupling means for attachment and removal of the lower part of said moisture cleaner to said dust suction head portion; and second coupling means for attachment and removal of the top part of said moisture cleaner to said connecting pipe. 
     
     
       3. A vacuum cleaner as in claim 2 in which the top and lower part of said frame are composed of a hinge member mounted in the center of the frame for attachment and removal of said moisture cleaner, the hinge member enabling the moisture cleaner to be folded. 
     
     
       4. A vacuum cleaner as in claim 2 in which the peripheral surface of said working roller is cylindrically shaped and has an uneven surface such that the moisture cleaner moves around between said working roller and said driven roller. 
     
     
       5. A vacuum cleaner as in claim 2, in which said first coupling means comprises a projection member which extends from both lower part sides of said frame and which has a cylindrical shape in order that the top part edge has a semicircle cross-section shape and a groove part formed at said dust suction head portion in order to accommodate said projection member, said groove part being composed of an open groove part and a interior groove part, the top part edge of said projection member passing through the open groove of the groove part when the moisture cleaner is attached, the top part edge moving down the interior groove such that the lower part of said frame can be attached and removed easily from said dust suction head portion. 
     
     
       6. A vacuum cleaner as in claim 2 in which said second coupling means is composed of a coupling projection formed at both top part sides of said frame and an expansive band formed with coupling holes at both edges thereof in order to insert said coupling projection therein whereby the coupling projection is inserted into said coupling hole such that the top part of said frame is removably mounted to the connecting pipe.
